Yeah, that's basically the same idea, but a bit longish for a one-liner, don't you think?

Dunno, seemed like the most straightforward answer to your question - just copy Win32\Autoglob.pm to wglob.pm ;-)

("'-M5;@ARGV=<*.srt>' -e'...'" actually doesn't save any characters over "-e'BEGIN{@ARGV=<*.srt>}...'")

Update: Regarding PERL5OPT, sure!

> `'-M5;@ARGV=<.srt>'`* nice, I didn't know that trick to add "normal" code after the `import;` part of `use 5` =) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

nice, I didn't know that trick to add "normal" code after the `import;` part of `use 5` =) Note unfortunately it doesn't end up inside the `BEGIN`: `$ perl -MO=Deparse '-M5;print "Hello"' -e 'print "World"' sub BEGIN { require 5; () } print 'Hello'; print 'World';` [download] The trick was added to perlsecret as the "Maori Farewell" by Discipulus after I posted about it here.

This is substantially the same logic quirk as the old "ShellShock" bug in bash. Both of these take an expected "data" value (although here the "data" is the name of a module to import instead of the body of a shell function) and then execute code given after that value in the same string. The best argument against calling this a security issue is that it must be either given on the command line or in `$PERL5OPT` — and you have bigger problems if either of those is within an attacker's control.

Well you know PERL5OPT doesn't allow `-e` and this most probably for security reasons. But this is a backdoor to do it nevertheless. Not sure if this must be reported. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]
